Do all Black Teas, Green Teas, and White Teas contain caffeine?

Yes. Black, green, and white teas, including decaffeinated versions, naturally contain caffeine. The decaffeination process cannot remove 100% of the caffeine, although on average, it safely removes approximately 99.6% of the caffeine. When a tea has undergone decaffeination, it is labeled as "Decaffeinated" Tea on our packaging.
